This case study shows how a Clare melon farm an reduce energy consumption and costs implementing the recommendations of an Energy Savings Program. The farm has already implemented VSD on 8 pumps, reducing the energy consumption for irrigation by 49%. Further savings can be achieved by upgrading irrigation, refrigeration and hot water systems, with energy savings estimated as 12% of total farm energy consumption (these savings have been calculated discounting the reductions achieved through the upgrades already implemented).
The Energy Audit recommended 3 main groups of projects: refrigeration, irrigation and pump laser alignments. Refrigeration system improvements are reducing annual costs by nearly $10,000 with a payback just over three years. The first of a number of pumps to be laser aligned is saving $5,500 annually and similar improvements are being found with pump refurbishments and variable speed controls. Added benefits include emission reductions of 75.3 t CO2-e.
